My best advice? Don't go out and find another "girlfriend".
Go have some fun, free of the "you didn't call"/"you forgot valentines day"/etc responsibilities otherwise you'll just be replacing her with another copy and probably end up right back where you started.
But if one pops up, great! If one doesn't, there's no rush. Luckily, us males age gracefully so there's no clock.
Hey, think of it this way, better this happen now than when you've got a house, a couple cars, a few kids and a set of in-laws, yes?
